HP Deskjet D1420 Printer - Manual (Page 54)

You need the following items to clean the print cartridges:
•
Distilled water (tap water can contain contaminants that can damage the print
cartridge)
• Cotton swabs or other soft, lint-free material that will not stick to the print cartridge
Be careful not to get ink on your hands or clothing as you clean.
To prepare to clean
1. Open the HP Deskjet cover.
2. Wait until the print cartridge cradle moves to the center of the HP Deskjet and is idle
and quiet.
3. Remove the print cartridges and place them on a piece of paper, with the copper strips
facing up.
CAUTION: Do not leave the print cartridges outside the HP Deskjet for more
than 30 minutes.
To manually clean print cartridge contacts
1. Lightly moisten a cotton swab with distilled water and squeeze any excess water from
the swab.
2. Gently wipe the print cartridge copper contacts with the cotton swab.
CAUTION: Do not touch the print cartridge ink nozzles. Touching the ink nozzles
will result in clogs, ink failure, and bad electrical connections.
1 Ink nozzles (do not touch)
2 Copper contacts
3. Repeat this process until no ink residue or dust appears on the swab.
4. Insert the print cartridges in the HP Deskjet, and then close the cover. For more
